You're going to run into countless problems like this unless you change
your expectations.  MinGW targets the native Windows API, that means no
POSIX emulation.  Windows does not have signals natively.  Yes,
technically MSVCRT supports an few signal functions for ANSI C
compatibility, but it's really meaningless once you read MSDN and find
out that they don't really work.

So, you can't just expect to compile your code unchanged with MinGW. 
You have to port it to windows.  If you don't want to do that, then
you'll have to use Cygwin.
